VS Code panel: a skill invocation with a long argument is rendered in full and covers the whole panel

Environment: Claude Code VS Code extension, Windows 11 Pro 10.0.26200, model claude-opus-5[1m].

When a skill is invoked with a long argument (e.g. /przelot <several KB of instructions>), the user message is rendered in full in the chat panel. There is no way to collapse it. With a multi-KB argument the message fills the entire panel and the rest of the session is unreadable until the user scrolls past it every time.

Expected: long user messages (or at least skill/command invocations) rendered as a collapsed preview with an expand control, the same way tool calls and results are collapsed.
